Air heat pumps have for ages been generally recognized as the cheapest retrofit install to save energy during the Finnish heating season. There was suspicion they could not produce enough energy during the very coldest time, which technically is true but we'd use fireplaces then anyway.
And ground/water heat pumps, while much more expensive to install, are even more energy efficient.
All of them cool as well, of course.
